[IOS] Page turning not working #85

Closed vitaliynester closed 1 year ago

vitaliynester commented 1 year ago

Hello @jmgeffroy I've noticed that page turning doesn't work on iOS devices. On Android, everything is fine, the problem occurs on iOS. Can you help somehow? Attached is a video of how it works.

Everything works fine if you set viewportFraction: 1

Hi @vitaliynester, thank you for these comments. We used viewportFraction < 1 to force prerendering (not just preloading) the next spine item, but this may be unnecessary now. We did a lot of investigation about it a few years ago when starting this project, and I need to check it again. Anyway, you'll be fine with viewportFraction = 1. The only potential issie is that you might encounter some small delays when arriving on a new spine item (typically, a chapter).
